An upper support structure is mounted on the carriage. The upper support structure includes a seat and an upper body support section pivotally connected thereto. A support arm is pivotally connected between the lower support structure and the upper body support section. An actuator is connected to the lower support structure. A lever arm is connected between the actuator and the carriage. Application of force from the actuator to the lever arm moves the carriage on the lower support structure. The support arm is arranged such that movement of the carriage toward the head end of the lower support structure produces a lifting moment on the upper body support section. The frame conventionally includes a mattress retainer mounted to the upper frame section to prevent a mattress positioned on the upper support structure from moving off the upper support structure.

SUMMARY OF THE INVENTION

The present invention contemplates a mattress retainer for a bed, more particularly an adjustable bed, and still more particularly a modular user-assembled adjustable bed.

When used with a most-preferred user-assembled modular adjustable bed, the preferred embodiment of the mattress retainer is fully compatible with both (1) shipping of the modular sections of the adjustable bed, temporarily fitting most preferably in a reversed position about the same foot-region frame section to which it will ultimately mount to retain the mattress, and (2) user erection of the modular adjustable bed which can be realized—with the mattress retainer as well as with the rest of the bed—by one single person without use of tools.

The preferred mattress retainer is of unitary construction, being mode of, most preferably, a single bent piece of metal, normally steel tube of, most preferably, square cross section. The mattress retainer so made is readily cleaned and sanitized in all sections. Indeed, as a unitary structure it is remarkably devoid of holes or cracks or crevasses or any surface features whatsoever, and may readily be cleaned by a hand-held cloth that is drawn along the tubular retainer.

The most preferred embodiments of the retainer are first as a relatively larger retainer for the foot section, and the foot of the mattress, of the adjustable bed. Other, relatively smaller, embodiments of the retainer can be fitted to the sides of the foot section of the adjustable bed, therein to retain the foot region of the mattress from slipping sideways off the bed. These smaller embodiments of the retainer are particularly effective with bed frames that are upholstered, and slippery to a mattress resting upon the upper surface.

The mattress retainer can mount, if desired, a fabric cover in its portions that are upstanding so as to server to retain the mattress upon the bed.

The mattress retainers are all compatible with each other in any combination, and may be selectively mounted and dismounted as requirements for, access to, and placement of the adjustable bed may change.

1. The Mattress Retainer in General

A mattress retainer of the present invention is for mountable and removable use with an adjustable bed having (1) a rectilinear foot-region frame section with (2) a planar upper surface upon rests the corresponding foot section of a mattress. The mounted mattress retainer basically operates to selectively “clip” this foot-region frame section, extending upwards at the foot region of the adjustable bed to retain the mattress upon the frame.

Mattress retainers in accordance with the present invention may be configured to retain the mattress from slipping off the foot, or to either side, of the adjustable bed. In essence the mattress of the adjustable bed may be selectively retained when, where and as required in its foot region, and should any retainer no longer be required or desired, it is simply removed.

The mattress retainer is preferably made from a contiguous piece of bent metal. It ships inverted in position on, most preferably, the foot-region frame section of a modular adjustable bed. It is erectable to operational position upon the bed by one person without use of tools.

2. The theory of a Mattress Retainer in Accordance with the Present Invention

For such an historically common object having such a mundane purpose as does a mattress retainer, the present invention contemplates a rather audacious, and highly effective, solution, Namely, a unitary tubular steel structural element (1) “clips” the foot region of the bed frame at each of two spatially separated locations, and then (2) rises upwards from and at each “clipped” location and (3) extends between the two locations so as to present a barrier at a side edge of a mattress that rests upon the bed frame, and upon the bed frame's foot region.

This design is arguably audacious because it is unusual to see a “clipped” affixation something of volume so large as is are the generally thick rectilinear sections of an adjustable bed.

The design is effective because, in subtending a goodly portion of two surfaces of the foot region of the bed frame, and also of the mattress that is retained, it offers the same stability and effective retention as was previously realized by substantial bold-on units. However, the “bed-frame-clip-type” mattress retainer of the present invention may readily be affixed and removed by hand, and by one person, without the use of any tools.

3. The Mattress Retainer of the Present Invention in Greater Detail

In one of its aspects the present invention may be considered to be embodied in a mattress retainer for use with a bed having a substantially rectilinear frame sections that have and present substantially planar upper surfaces upon which rests a mattress that is retained upon the bed.

The mattress retainer so deployed consists of a contiguous piece of tubular metal. This tube is bent so as to clip a section of the bed frame in two spaced-parallel regions, each spaced-parallel clip extending from an edge of the clipped section of the bed frame so as to act against top and bottom surfaces of the bed frame equivalently as a common paper clip would act to compressively clip a thick sheaf of papers. These two “clip” sections are connected by an upstanding “U”-shaped section between the two-spaced parallel clips that engages a mattress upon the bed at the edge of the clipped section, and that keeps the mattress from sliding off the section and off the bed.

This mattress retainer can be used at a foot of a foot-region frame section of the adjustable bed, there serving to prevent the mattress from sliding off the foot region of the bed. It can be used at either side of the foot-region frame section of the adjustable bed, there serving to prevent the mattress from sliding off the side of the foot region of the bed. It can even be used at a head of a head-region frame section of the adjustable bed, there serving to prevent the mattress from sliding off the head of the bed.

In another of its aspects, the present invention can be considered to be embodied in a mattress retainer for use with an adjustable bed where the bed has a substantially rectilinear foot-region frame section having and presenting a substantially planar upper surface upon which resides a foot region of the mattress. The retainer serves to retain the mattress upon this foot region.

So used and adapted the mattress retainer consists of a contiguous piece of bent metal, preferably steel tubing of round or, most preferably, square cross-section. This bent metal piece is disposed partially upon the foot-region frame section, partially under the foot region of the mattress, and partially upstanding at the foot of the mattress. So positioned and disposed it there retain the mattress upon the fame.

An embodiment that retains the mattress from slipping off the foot of the foot section of the adjustable bed is symmetrical about an imaginary vertical plane along a longitudinal centerline of the bed. An embodiment that retains the mattress from slipping off the sides of the foot section of the adjustable bed is symmetrical about an imaginary vertical orthogonal to a longitudinal centerline of the bed.

In detail, each symmetrical half of the bent metal piece (1) proceeds from a vertically upstanding extension contacting the rectilinear foot region frame section in a position opposite to the foot of the bed, to (2) extend rearward under the foot frame section to the foot edge of the bed, there (3) proceeding upwards and around the foot edge region of the foot frame section and then (4) forming a substantial loop directionally first away from and then back to the foot of the bed and its foot frame section. Finally, each symmetrical half of the bent metal piece (5) extends first upwards and then laterally centrally so as to, in combination with the symmetrical half, produce a mechanically stable upstanding barrier at the foot of any mattress upon the foot frame section of the bed. The barrier serves to retain the mattress upon the foot frame section and upon the bed.

The mattress retainer is preferably for use with an adjustable bed wherein the foot-region frame section is an adjustable section of the adjustable bed.

It is more preferably for use with an adjustable bed that is modular, in which use the mattress retainer is shipped with the foot-region frame section of the modular adjustable bed. Most preferably the retainer is reversed relative to mattress surface of the foot-region frame section during this shipping.

In greater detail, the substantial loop formed by the piece of bent metal that constitutes the mattress retainer—the loop that proceeds directionally first away from, and then back to, the foot of the bed and its foot frame section—is more particularly in the substantial shape of a single loop of a paper clip. In this contour it can be analogized that each symmetrical half of the bent metal piece serves to clip the foot-region frame section of the bed.

These and other aspects and attributes of the present invention will become increasingly clear upon reference to the following drawings and accompanying specification.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of a first preferred embodiment of the mattress retainer of the present invention shown in isolation,

FIG. 2 is a diagrammatic perspective view of the various embodiments of the mattress retainer of the present invention—a first of which embodiments was previously seen in FIG. 1—fitted in operational positions upon an adjustable bed that is shown in phantom line.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention is directed to a mattress retainer that is particularly for use on an upper surface of a bed is adjusted in contour, or adjustable bed. A mattress that rests upon this surface—and any person(s) upon the mattress—may slide in position, including off the frame of the bed.

To prevent this undesired movement a mattress retainer serves to hold the mattress in acceptable position during all contour adjustments of the adjustable bed.

A first preferred embodiment of the mattress retainer 1 of the present invention is shown in perspective view in FIG. 1. The retainer is symmetrical about an imaginary point A′ of an imaginary vertical plane A, and about the plane A itself. The head of the bed frame (shown in FIG. 2), and the bed, is in the direction of arrow B. The foot of the bed frame, and the bed, is in the direction of arrow C.

Each symmetrical half of a bent metal retainer has vertically upstanding extensions 11 a, 11 b contacting a rectilinear foot-region frame section in positions opposite to the foot of the bed frame (shown in FIG. 2). The base of these extensions 11 a, 11 b extend rearwards, and in the direction of arrow C, in respective members 12 a, 12 b. These members 12 a, 12 b will lie under the foot-region frame section 51 of the bed 5 (shown in FIG. 2), and bend upwards and around the foot-edge-region of the foot-frame-section 51 at 13 a, 13 b. The members then continue respectively as 14 a, 15 a, 16 a, and as 14 b, 15 b and 16, to form a substantial loop that is in direction first away from—i.e., in the direction of arrow B—and then back towards—i.e., in the direction of arrow C—the foot of the bed and of the bed's foot frame section 51 (shown in FIG. 2). At this point through members 16 a and 16 two spaced-apart, spaced-parallel, “clips” have been formed embracing, and “clipping” the foot-region frame section 51 of the bed 5 (shown in FIG. 2).

Finally, each symmetrical half extends first upwards in members 17 a, 17 b and then towards each other laterally centrally, and in union with the other symmetrical half, via the member 18.

The combination of all members produces a mechanically stable upstanding barrier 17 a, 18, 17 b at the foot of any mattress upon the foot frame section 51 of the bed 5. This barrier serves to retain the mattress upon the foot frame section 51 and upon the bed 5.

The first preferred embodiment of the mattress retainer 1 of the present invention, previously seen in FIG. 1, is shown in diagrammatic perspective view fitted in operational position upon the foot fame section 51 of an adjustable bed 5 in FIG. 2. The bed 5, and its foot frame section 51, are both shown in phantom line for not being part of the mattress retainer of the present invention.

The first preferred embodiment of the mattress retainer 1 of the present invention, previously seen in FIGS. 1 and 2, is shown accompanied by second embodiments 2, 3 of the mattress retainer that serve to retain the mattress (not shown) from slipping off the sides of the foot frame region 51 (shown in FIG. 2) of the adjustable bed 5 (shown in FIG. 2).

Also shown in FIG. 22 is a mattress retainer for a head frame region 54 of the adjustable bed 5. It will be understood that sections 51-54 of the adjustable bed 5 are moveable in angle relative to one another, and that this is the reason that a mattress (not shown) needs be maintained from slipping off the bed 5.

The first preferred embodiment of the mattress retainer 1 of the present invention, previously seen in FIGS. 1-3, is fitted in reverse position to the foot-region frame section 21 of the modular adjustable bed 5 (both previously seen in FIG. 2 and again shown in phantom line) during shipping of this modular foot-region section 51 of the adjustable bed 5.

Clearly the concept of “clipping” the foot-region frame-section of an adjustable bed could be realized by members other than 14 a, 15 a, 16 a and 14 b, 15 b, 16 b shown in FIG. 1. Still other contours could be accorded to other members consistent with their functions. According to these variations, and still others within the skill of a practitioner of the bed, and adjustable bed, and modular adjustable bed arts, the present invention should be considered in accordance with the following claims, only, and not solely on accordance with those embodiments within which the invention has been taught.
